Chemistry Help with density!!!!?

Question

An empty Erlenmeyer flask weighs 241.3 g. When filled with water (d=1.00 g/cm^3), the flask continues to weigh 489.1g. whats is the flasks volume? how much dose the flask weigh when it filled with cholorform ( d= 1.48 g/cm^3)

Please help I think i got the first part right but not to sure about the second part can someone please help

Answer 1

489.1g-241.3g = 247.8g ( The weight of the water )

Water weight 247.8g *  (1/density of water) 1cm^3/1g = 247.8 cm^s (Volume of the Flask)

Volume of the Flask (247.8 cm^3) * Density of chloroform (1.48g/cm^3) = 366.7 g of chloroform (weight of chloroform needed to fill flask)

Weight of Chloroform (366.7g) + Weight of the Empty Flask (241.3g) = 608.0g (weight of flask filled with chloroform)

Answer 2

489.1 g (flask+ water) - 241.3 g (flask) = 247.8 g (water)

247.8 g / 1.00 g/cm^3 = 247.8 cm^3

247.8 cm^3 x 1.48 g/cm^3 = 366.7 g chloroform

366.7 g (chloroform) + 241.3 (flask) = 608.0 g (flask+chloroform)

Answer 3

Density (D) = Mass (M) * Volume (V)
